Prof. Ian McLean9/1/08, 1:50 PMApplications in Astronomy and AstrophysicsKeynote talkThe set comprising of silicon charge-coupled devices, low band-gap infrared arrays and bolometer arrays provide astronomers with position-sensitive photon detectors from the X-ray to the sub-mm. In recent years the most significant advances have occurred in the near-infrared part of the spectrum because not only have the detector formats caught up with those of CCDs but also because the...Go to contribution page

Dr Christopher Saunter (University of Durham)9/1/08, 2:30 PMApplications in Astronomy and AstrophysicsOral ContributionAdaptive Optics systems measure and correct dynamic optical distortions, often atmospheric turbulence, to improve overall system performance. Such systems have grown from their astronomical inception in 1953 to cover many fields including ophthalmology, high power lasers, communication, optical storage and astronomy. There are many different systems but common to all is the need to...Go to contribution page

Dr Ives Derek9/1/08, 2:50 PMApplications in Astronomy and AstrophysicsOral ContributionElectron multiplication CCDs have been commercially available for the last few years but have yet to make wide impact in the astronomical community. They have specifically been designed to use an avalanche gain process during the serial charge transfer to give sub-electron read out noise. In all other respects they are identical to the very latest generation of CCDs. They have been used with...Go to contribution page

Dr Adam Woodcraft9/1/08, 3:10 PMApplications in Astronomy and AstrophysicsOral ContributionSub-mm astronomy has seen an explosive growth in recent years. This has been driven by improvements in detector technology, and in particular the move from single pixel instruments to ones containing arrays of hundreds and even thousands of pixels. Sub-mm detectors are different from those used in astronomy at most other wavelengths in that they are not produced commercially. Instead,...Go to contribution page

Lawrence Jones (STFC Rutherford Appleton Laboratory)9/1/08, 3:30 PMApplications in Astronomy and AstrophysicsOral ContributionHEXITEC is a collaborative project with the aim of developing a new range of detectors for high energy X-ray imaging. High energy X-ray imaging has major advantages over current lower energy imaging for the life and physical sciences including improved phase contrast images on larger, higher density samples and with lower accumulated doses. However, at these energies conventional silicon based...Go to contribution page
